2.6.27-stable review patch. If anyone has any objections, please let us know.

------------------

From: Jiri Slaby <jirislaby@xxxxxxxxx>

commit 7aed55d1085f71241284a30af0300feea48c36db upstream.

Impact: fix debug/crash printout

Since errorcode is popped out, RIP is on the top of the stack.
Use real RIP value instead of wrong CS.
